Can anybody tell me some way to return all numbers from a string such as : 99, 0100, 1.2345 ... ? Thanks so much

Do you mean you have a string separated with commas in the format number,number,number ?

If so, then the following is for you

PHP Code:

$string = "99,0100,1.2345";

$list = explode(',', $string);



for ($i = 0; $i < count($list); $i++) {

     echo $list[$i];

} 

Untested but it should work.

Ah oh, thanks for your help but in my first post I have caused misunderstanding. I was going to ask for how to return all numbers such as : -99, 0100, 1.2345 ... ( integer, negative numbers, dotted ... ) in a string but I can't edit my post.

That code should be fine for that too. If you have an organised string where the values are all separated with a common delimiter (in this case a comma) then the explode() function can split that up for you.

If your string may contain things other than numbers, it might be worth running an is_numeric() check on each part for validation.

Revised (and still untested) code

PHP Code:

$string = "99,0100,1.2345";

$list = explode(', ', $string);



for ($i = 0; $i < count($list); $i++) {

     if (is_numeric($list[$i])) {

          echo $list[$i]; // Will print only numbers from the list

     }

}
